Of course, I don't see the 'emacs -Q ...' command. That was me having
a spot of bother copying-and-pasting from an emacs -Q session. I'm
used to Emacs automatically copying its region into X's copy-paste
buffer, which 'emacs -Q' didn't do for me.
I've run 'gdb' from inside the src directory so that the 'xbacktrace'
command will be defined, but the output was less than interesting:
------
Program received signal SIGSEGV, Segmentation fault.
choose_face_font (f=0x864a3d8, attrs=0x8703898, fontset=<value optimized out>,
c=3840, needs_overstrike=0xbfbd2fe8) at xfaces.c:6684
6684 enum xlfd_weight got_weight = best->numeric[XLFD_WEIGHT];
(gdb) xbacktrace
(gdb)
-------
I can set a breakpoint and run some other gdb commands if there's
something that it would be helpful for you to see around the time it
crashes.
